ABSTRACT
Background and Aim: Drip irrigation or localized irrigation, is the provision of water localized near the roots of plants, with reduced doses but at high frequencies. This work aims to design a drip irrigation system by photovoltaic pumping at the National School of Agriculture and Livestock (ENAE) of Tolo in Mamou for the irrigation of market gardening crops (onion, cabbage, tomato and eggplant).
Method: The approach followed for this study consists of: field investigation (choice of site, types of soil and crops, water needs); the sizing of system parameters (drip irrigation and photovoltaic solar pumping).
Results: The main results of the work are: Evapotranspiration (8 mm/d); crop water requirements (2.5 mm/day); watering duration (3 h/d); number of gutters (125); Length of the ramp (50m); ramp diameter (16 m); ramp spacing (40 cm); boom flow rate (5 l/h); daily water requirements (30 m3); HMT (26m); daily energy (3000 Wh/d); field power (1200 Wp), number of panels (12, type 100Wp); Regulator (60 A); inverter (1400 W); number of batteries (8); hydraulic power of the pump (125 W); installation diagram and estimated cost of creating the system (200150000 GNF).
Conclusion: The results of this study will serve as a basis for the creation of a drip irrigation system using photovoltaic pumping for market gardening in the agricultural plains of ENAE from Tolo to Mamou.
Keywords: Drip irrigation, market gardening, photovoltaic pumping.
